MSM66577 Family

4/34

6. Multifunction PWM

The family supports both 8- and 16-bit PWM operation.

Choosing between the time-base counter output or overflow from an 8-bit auto-reload timer as the PWM counter

clock source provides a wide number of possibilities over a broad frequency range. The 16-bit PWM configuration

supports a high-speed synchronization mode that generates a high-precision output signal with less ripple suitable

for digital-to-analog control applications.

7. Programmable pull-up resistors

Building the pull-up resistors into the chip contributes to overall design compactness.

Making them programmable on a per-bit basis allows complete flexibility in circuit board layout and system

design. These programmable pull-up resistors are available for all I/O pins not already assigned specific functions

(such as the oscillator connection pins).

8. Wide support for external interrupts

There are a total of nine interrupt channels for use in communicating with external devices: eight for maskable

interrupts and one for non-maskable interrupts.
